To al! whom it may concern Be it known that I, Jnssn RosnNnAUiu, a citizen oil? the United States, resident of Mount Vernon, in the county of Posey and State of Indiana, have made a certain new and useful Invention in Loclzing Devices for Vehicle llhcel-Riin Flangcs; and I declare the :following to be a full, clear, and exact description of the same, such as Will enable others skilled in the art to which it appertains to malte and use the invention, reference being had to the accompanying drawings, and to letters or figuresL of reference marked thereon, which form a. part of this specification.

Figure 1 is a section on the line 1-1, Fig.

' 3, and shows the device as applied to the rim of a vehicle wheel, also shown in section,

.the released positions of parts being shown in dotted lines. Fig. 2 is an inside face view of the invention. Fig. 3 is a section on the line 3-3, Fig. l. Fig. 11 is a detail side View ol one of the eccentries and its lever handle. Fig. 5 is a side viewof aportion of a wheel havingthe invention applied thereto.

The invention has relation to locking devices for the detachable tire retaining langes of vehicle Wheels, designed to facilitate the removal of the flange and of the tire from a' wheel, and the locking in place 'of the tire upon the Wheel.

The invention consists in the nQvel construction andcombinations of parts as hereina'ter set forth.

Int-he accompanying drawings ill .ustrat-' ing the invention, the numeral l, designates the rim or telly of the wheel, having at its inner, side the tire retaining flange 2, and at its outer side the detachable tire retaining flange or ring 3, said telly having a flat outer ciilcumferential surface 4, without groove orshoulder that will obstruct the removal of the detachable iaiige or of the tire.

Secured to the folly usually by bolts or screws 5, are a. plurality o1? attachments or casings 6, separated by suitable intervals,

and having each a radial slot 7,. engaged by a radially 'reciprocating clamping member ,or locking bolt 8, designed to overlap` the detachable' flange 3 to hold itin position against the tire in place upon the wheel,sa1d

bolt being capable of Withdrawal in the slot :o allow removal o1 thc flange and of the Each of the locking bolts is operated by suitable means preferably an eccentric or` full lateral throw, so that any strain of the.-

tire upon the detachable flange tending, to tire displacement, Will press the outer flat face or edge of the bolt all the more securely against the flat face of the casing to maintain the locking engagement. Each eccentric is provided with a suitable handle 15.

The invention is designed for convenient attachment to Wheels now in use Without perforation or slottine of the felly or rim base. When the locking bolts are released they will remain in released position owing to the comparative weight and the friction of the parts.

What l claim is:- A 1. In a vehicle wheel, the' combination with a felly, a tire rim and a laterally movable tire retaining ring, of an attachment having a flat inner face, a rotary cam mounted in said attachment and having its` plane at right-angles to that of the wheel,

and a radially movable clamping member upon said cam and overlapping said retaining ring to lock said ring in position, said member being provided with a `fiat outer face having in locking position 'bracing engagement with the flat inner face of said attachment. f;

2. In a vehicle Wheel, the combination with a felly, a tire rim and a laterally mov- .able tire retaining ring, of an attachment having a radial slot and a at inner face, a

rotary cam mounted in said attachment and having its longitudinal axis parallel with the planey of the Wheel, 'said cam having movement in a plane at right angles to that of the wheel, and a radially movable clamping member upon said cam and overlappmg said retaining ring to lock said ring in postion spaced apart from said inner face of lnon, sgml. member being provlded wlth a the attachment. 0 Het outer face havmg 1n ockmg posltlon In est'lmony Wheleof aHXlmys'lg-nature, bl'ucmg engagement Wlth the Het mner *face 1n presence 0i' two Wltnesses.
